Depth of field can be a somewhat confusing topic to get to grips with if you’re new to photography. That is to say, it’s easy to see what depth of field is, but it can be tricky to understand what elements can cause it to change, whether intentionally or by accident. In this video, photographer Kellan Reck takes a look at depth of field and explains the variables that can affect your depth of field.
Manual exposure. It’s probably the scariest term out there for new camera owners. Stepping out of automatic or semi-automatic exposure modes for the first time can be a daunting task. When you’ve only ever shot in the automatic modes, understanding the manual and the exposure triangle can be difficult to wrap your head around.
Well, this 26-minute video from photographer Sean Tucker should help to demystify it for you. He goes in-depth to break everything down to the basic fundamental principles. He explains what each of the three settings means, how they function, and how they all work together to create a good exposure.
The inverse square law (ISL) is one of those principles of photography that drives people crazy. It’s a fairly simply concept that’s broken down into a rather confusing sentence. It states that the intensity of an effect such as illumination or gravitational force changes in inverse proportion to the square of the distance from the source. That, to most people means absolutely nothing.
So, in this video, photographer Joe Edelman is here to explain it in straightforward terms. In his usual way, Joe has lots of diagrams and practical examples to illustrate what it’s all about. The ISL can be a difficult one to wrap your head around at first. Once you understand it, though, it all makes complete sense. You’ll wonder how you ever got on without knowing it.
Understanding light is one of the main conditions for successfully illuminating our subjects in photography or videography. Matthew Rosen from KINETEK explains some basic principles of lighting, and how to apply them on different types of surfaces. It’s explained in a simple way, with comprehensive examples, so it will be very useful and easy to follow for all the newbies.
The aperture is one of the most difficult things for new photographers to wrap their head around. The number system seems confusing (smaller number, bigger hole), depth of field, how it affects exposure. It’s a lot to take in all at once.
This five minute animated video from YouTuber Apalapse goes over everything you ever needed to know about your camera lens’s aperture. It goes over some of the issues associated with picking which type of lenses you might want to buy, too.
When I first started photography, I struggled a lot with lighting. In the beginning, we are often told to shoot our subjects in open shade. If you don’t know how to do this properly, then the results can be disastrous: faces with dark shadows, eyes with no depth, overexposed backgrounds, etc.
To be able to create composites using your photos, you must first know how to take a properly-lit image. If the lighting in your foundation photo is off, your composite will not look right, even with heavy editing. The following are four basic lighting principles I wish I knew in the beginning of my photography career and that I’ve personally had a lot of success with:
Up front let me say “field curvature” is not that pesky problem where images with straight lines in the frame seem to bow in or out as you move towards of the corners, that would be distortion, which comes in two core flavours, barrel and pincushion, with moustache as a somewhat recalcitrant but rare third option. There is a relationship between distortion and field curvature, but we won’t be getting into that in this article.
Field curvature can be a right little bastard, causing time dilation, warping gravitational fields, interfering mercilessly with photons and fooling with quantum calculations…..well actually it won’t do any of those things but it can indeed be tricky if you don’t know what it is and how it might impact on your photos.
Without light, there would be no such thing as photography. But simply having light isn’t enough. Cameras turn our three dimensional world into a two dimensional flat image. Light allows us to bring that third dimension back into our images. In order to do that, we need to know how to read it and how to control it.
In the first of a new video series from The Slanted Lens called Laws of Light, Jay P. Morgan looks at the humble sphere. And why not? It’s the perfect representation of three dimensionality which lets you easily see all the principles of light. I’ve seen similar demonstrations in the past using everything from pool balls to bowling balls.
